Embodiment Construction
[0045]Techniques for video and image stabilization are provided. Video stabilization aims to stabilize hand-held videos to eliminate hand tremor and shake. Camera shake can be minimized using known image analysis techniques to minimize offsets between consecutive frames of a video. However, all these techniques suffer from an inherent limitation that they cannot distinguish between camera motion and subject motion. Furthermore, these techniques are affected by motion blur, changes in lighting conditions, etc.
[0046]Integrated inertial MEMS sensors have recently made their way onto low-cost mobile devices such as consumer cameras and smart phones with camera capability and provide an effective way to address image distortion in videos and pictures. Accordingly, techniques for video and image stabilization provided herein utilize sensor information for improved stationary object detection. Gyroscopes, accelerometers and magnetometers are all examples of such sensors. Especially, inerti...
